3.5.3 Description of Sample Metadata Files - optional
This section describes the contents of sample metadata files. Once the user is familiar with the structure of the metadata file, the user should be able to gain information from all of the metadata files.
The first three lines of a log file identify the Level 1 processing command from which the log file was generated, the Hyperspectral Image Processing (HIP) software version number, and date and time file was processed. In this case, the command used to create the file is “cubeavg”, version 1.1 of HIP was used and the level 1 processing was performed on June 5, 2000.
The next set of information contains the command line arguments as well as file parameters associated with the input (source) and output files. The file parameters include the file name, file type, dimensions, data type, byte order (big-endian), and pixel order (BIL or BSQ)) are given for each input and output file. The file name includes the pathname in the level 1 processing system. When appropriate the metadata file will include command line options.

The end of a log file contains processing Results or Summary information. In this case, the file is reporting the average dark pixel value for the dark file used in the dark subtraction process. The subtracted dark file is 256 FOV pixels x 242 spectral pixels in size and averaged over ~220 frames.
The average dark file is supplied as MD3. The average dark pixel value reported in MD5 represents the average value over all FOV and spectral pixels and is used on the Quality Assurance form (MD11) to track instrument performance.

Echo removal log (MD8) has the same general format as Average Log (MD5) but it reports that the echo correction process has been completed. At the end of this log file, the specific echo correction file used in the correction process is identified (ratio.txt), along with the number of the band at which echo correction began. The VNIR focal plane covers spectral bands 1-70, so it is expected that echo correction, which is required only in the SWIR, would start at band 71.

Smear Removal Log (MD9) has the same format as Echo Removal Log (MD8) but there is no file used in the smear correction process. Again, the band at which smear correction begins is reported.
The VNIR focal plane covers spectral bands 1-70, so it is expected that smear correction, which is also only required in the SWIR, would start at band 71.

Figure 15 : Example (MD 9) - Smear Removal Log
Pixel Repair Log (MD10) has the same initial format as the preceding metadata files but it reports on the repair of known bad pixels. The specific file used to identify the known bad pixels is identified
(badpix.txt). The results summary in this metadata file is in two parts. The first part identifies the known bad pixels, by band or spectral pixel number and sample or FOV pixel number, and is essentially a printout of badpix.txt. This file will be updated over the course of the mission. The second results section indicates how the values of these known bad pixels are replaced. For FOV locations other than 1 or 256, the value is replaced by an average of the value in the neighboring FOV pixels (e.g., 50% of (61, 92) and 50% of (61,94) for bad pixel (61, 93)). FOV pixels 1 and 256 are replaced by the value of the neighbor pixel, 2 or 255.
